COOLING DEVICE FOR VAPOR ELECTRIC APPARATUS.

- Patented Feb. 11,1913.

Original application filed July 7, 1904, Serial No. 215,576. Renewed september 11, 1908, Serial No. 462,654.

Divided and this application filed March 18, 1909. Serial No. 484,185.

To all whom it may concern:

resident of Ringwood Manor, county of Passaic, State of New Jersey, have invented certain new and useful Improvements in Cooling Devices for Vapor Elect-ricApparatus, of which the'following is a specification. I v

The present invention relates to means for controlling the temperature of the vaheat, said last named means belng within por in vapor electric apparatus such as is represented by the well-known mercury vapor converter. The amount of condensation in such apparatus may be made subject to control by various means or devices, and the present invention is concerned with providing suitable means for the purpose indicated.

The invention will be fully understood by reference to the accompanying drawing which is a diagram of an apparatus having my invention applied thereto.

In the drawing 1 is the container of a mercury vapor converter, 2 is the negative electrode thereof, which is usually of mercury or other suitable material, the vapors of which may be condensed by cooling devices. Positive electrodes are shown at 3, 4, 5 and 6, in the number required. In the normal operation of a converter of this type a portion of the negative electrode is vapor.- ized and a portion of the vapors are necessarily condensed in order to maintain the successful operation of the device. For this purpose I pass through the container 1,tubes 8 and 9, which are joined at their opposite ends outside the container and connected on the one hand through a suitable pumping apparatus, 10, with a tank, 11, containing water 'or other coolin fluid, andv on the The temperature of the vapor in the container 1 may be regulated at will by opcrating the pump 10, the water or other condenser surface may be used as tute for'the tubes shown.

cooling fluid being caused to pass through the container by way of the tubes 8 and 9.;

I claim as my invention:

1. The combination with a vapor device comprising a container and electrodes therein, of means for generating heat within said container, and means for removing said the container and including a circulating cooling liquid.

liquid cooling means within the container,

said means-consisting of a circulating liquid adapted to condense said vapor.

3. The combination with the container of a vapor device, of electrodes therein, a cooling surface inside the container independent of the electrodes, and means for causing the circulation of a cooling material for cooling the said surface.

4. The comb'inationwith a vapor device comprising a container and electrodes therein, of a cooling pipeor pipes traversing the container and means for causing the circulation of a cooling material through said pipe or p1pes.

5. The combination with a" vapor device comprising a container, a negative electrode and a plurality of positive electrodes therein,-of a cooling surface inside the container and independent of the electrodes, and means for causing the circulation-of acooling material for cooling the said surface.

6. The combination with a vapor device comprising a container and electrodes therein, of means for generating heat within said container, and means for v removing said heat, said last named means including a cooling liquid, circulating in a closed circuit passing through said container.
